Stacked on top of #1157 (
skosuri/clustermesh-scale). Do not merge until #1157 is merged; review/merge order matters.This PR continues the ClusterMesh scale-test scenario with Phase 3 work — moving from harness validation (2 small clusters) to real scale measurement across cluster-count tiers.
Phase 3 Deliverables
azure-5.tfvars,azure-10.tfvars,azure-20.tfvarsand corresponding pipeline matrix entries. Each tier: validate quota, validate peering count (N·(N-1) at separate-VNet mode — 380 at N=20), tune CL2 timeouts, document breaking points.utils.run_cl2_command(currently synchronous,modules/python/clusterloader2/utils.py:66-72) and confirming the AzDO agent has CPU/RAM headroom for N concurrent CL2 + Prometheus.Out of Scope (deferred to later phases / pre-merge of #1157)
